Researchers just uncovered more about the asteroid that killed the dinosaurs 66 million years ago

Researchers have identified the asteroid responsible for the dinosaur extinction as an "oddball" meteorite. New findings indicate the object possesses unique nickel fingerprints that help distinguish its chemical composition from previously assumed types.

Coverage from Sci.News, ZME Science, New Scientist, Phys.org, and The Independent emphasizes that the chemical makeup of the space rock suggests the extinction event was more complex than earlier models described. These outlets highlight that the identification of this specific class of meteorite provides new data on the history of the impact.

Future reports will track whether additional analysis of these nickel signatures changes the current understanding of the impact's dynamics. Coverage does not yet specify how these findings will affect existing models of the mass extinction.
